Unit two of the "Carbon Connections: The Carbon Cycle and the Science of Climate" curriculum examines the role of carbon and the carbon cycle in current climate. Students discover how carbon in Earth's system is monitored and also investigate the...(View More) roles of photosynthesis, cellular respiration, and humans in the carbon cycle and climate. The unit contains five lessons entitled: Moving Carbon, Exploring Limits, The Breathing Biosphere, Carbon Cycling, and Earth Takes a Breath. Each of the five lessons includes focus questions, hands-on activities, virtual field trips, and interactive models.(View Less)

Unit one of the "Carbon Connections: The Carbon Cycle and the Science of Climate" curriculum introduces the role of carbon (as carbon dioxide) as an atmospheric indicator. Students examine the impact of geologic and climatic history on current...(View More) climate by using computer models, measurements and the geologic record of past climate indicators. The unit contains five lessons entitled: Carbon Fizz, Carbon from the Past, Carbon Forcing, Global Connections, and Core Connections. Each of the five lessons includes focus questions, hands-on activities, virtual field trips, and interactive models.(View Less)

Unit three of the "Carbon Connections: The Carbon Cycle and the Science of Climate" curriculum examines the role of carbon and the carbon cycle in future climate. Students discover how scientists determine Earth's average temperature and the role of...(View More) climate models in understanding the size of some forcings on temperature. Students are challenged to reduce their electrical energy usage and to critically evaluate claims about carbon and climate. The unit contains five lessons entitled: Your Temperature Connections, Testing Forcings, Future Forcings, It Starts at Home, and Climate Claims. Each of the five lessons includes focus questions, hands-on activities, virtual field trips, and interactive models.(View Less)

This is a lesson about the size and scale of planets in the solar system. Learners will kinesthetically model the order of the planets outward from the sun. Then they will use a string and beads to create a model to represent the relative distances...(View More) between the planets. Finally they will explore another model (using a beach ball for the sun) to discuss relative size of the planets to the sun. The lesson uses the 5E instructional model and includes teacher training, pacing guides, essential questions, a black-line master science notebook, a student presentation booklet, supplemental materials, and vocabulary for both students and teachers. This is lesson 1 of the Mars Rover Celebration Unit, a six week long curriculum.(View Less)

This is an activity about sampling in astronomy. Learners will make a sampling window in order to estimate the number of stars in the sky visible to the unaided eye. After, they will discuss how to estimate the effect of different variables on their...(View More) counts, such as sky brightness, dark adaptation, cloud cover, etc. Please note use of a clear night sky is optimal for this activity.(View Less)
